It's shaping up to be a golden age for enthusiasts, and what's under the hood is becoming more important than ever.

The V8s

Right now, the 5.0-liter Mustang GT has the lead among Detroit's V8 muscle cars in the power department, though there's a caveat. The 435-hp output of the 5.0-liter 'Stang is ahead of the 6.2-liter LS3 V8 Camaro SS, which is rated at 426 ponies. It's also better than the 5.7-liter V8 Challenger R/T's 375 hp.

But, it trails the 6.4-liter V8 used in the 392 Challenger, which makes 485 hp. Blue Oval enthusiasts could argue the 392 is a sort of "Hellcat Lite," and not the GT's true competitor.

The tables are turned in the torque department, as the V8 Stang summons 400 lb-ft, which is behind the Camaro SS (420 lb-ft), the Challenger R/T (410 lb-ft) and the 392 (475 lb-ft).

Of course, we're just talking about the 2015 Mustang's competition, and since we don't know what's in store for the SVT-tuned example yet, we're leaving out any comparisons to the Camaro Z/28 and ZL1, as well as the previously mentioned, 707-hp Challenger Hellcat.

The V6s

Among V6s, the Camaro is the decided leader in power, boosting 323 hp, well ahead of the Challenger's 305 hp and the now-detuned Mustang, which dropped to an even 300 hp this year.

The Blue Oval does pack the most torque among six-cylinders with 280 lb-ft, just ahead of the Camaro's 278 lb-ft and the Challenger's 268 lb-ft.

The Wildcard

Of course, we're referring to Ford's EcoBoost inline four-cylinder, which pushes out 310 hp and an impressive 320 lb-ft from a turbocharged 2.3-liter mill. Neither Ford nor Chevy have anything similar in their current muscle car lines, and if there are any undecided potential buyers in this died-in-the-wool segment, it could prove to be a game-changer.

Tipping The Scales

The turbo four is also the lightest Mustang and the lightest car among these offerings from Detroit, weighing 3,524 pounds. The V6 'Stang is just two pounds heavier though, which puts it well ahead of the V6 Camaro (3,702 pounds) and Challenger (3,834 pounds).

This trend continues among the V8s, as the Mustang GT is 3,705 pounds - just three pounds heavier than the lightest Camaro V6. The eight-cylinder Chevy comes in at 3,908 pounds, which is still lighter than the Challenger's weight of 4,082 pounds.

So those are the cold, hard numbers. Objectively there are definite winners and losers, depending on what you value in a sporting automobile. But in the end, this segment has always been about more than the numbers. If anything, spec sheets trivialize it. Muscle cars are about the visceral experience from behind the wheel. Pick your favorite, plunk down your cash and hit road. Who are we to tell you that you're wrong?
